SEAM FOR BOOTS AND SHOES.

SPECIFICATION forming part of' Letters Patent No. 230,654, dated August3, 1880. Application filed May 28, 1880. (No model.) Patented in CanadaJanuary 10, 1880.

drens, boys, or youths, but will be found specially useful in cases inwhich eXtra strength of construction is required and the boot or shoe isexposed to more than the ordinary wear and tear and to dampness. brieiiydescribed as consisting in securing together the edges of the severalpieces going to make up the uppers' of boots and shoest'. c., making theseams-by means of rubber I cement placed between their overlappingsurfaces and a continuous lille of y'rivets passing through both pieces.

In the drawings hereto annexed, and forming part of this specification,Figure l is a view of a seam made according to my invention; Fig. 2, asection through same, and Fig. 3 a view of a boot embodying myinvention.

Similar letters of reference indicate like parts.

My improved water-proof seam is construct ed by lirst placing betweenthe pieces of leather to be joined (marked A andB inthe drawings) aclose layer of rubber cementv sufficient to keep out water but not tojoin the pieces securely together. I then run a line or lines ofstitching, as shown at el d, through the pieces which overlap eachother, after which I drive through both thicknesses rivets C, at shortdistances apart, in a continuous line throughout the seam. From this itwill be understood that the rubber cement obviates all It maybe chanceof wet oozing through'the seam. The stitching vprevents the edges oftheJ leather from turning up, besides making the seam more compact, andthe continuous line of rivets strengthens the joint and has the eliectof making the seam absolutely indestructible.

The rivets used may be of any metal of which they are usually formed;but, in boots of a superior class, of copper or other substance notaffected by wet. In all cases they will be inserted so as not-to strikeout the pieces embraced in them, which might weaken the leather and makethe boots liable to leak, my invention being specially intended toovercome this difficulty.

It will be seen that by this invention a seam is formed at very littlecost, at the same time being water-tight and of great strength and 6odurability, and that consequently boots made `in this way will be foundspecially serviceable for men employed in lumbering, for fishermen, andrailway navvies, as from their non-liability to rip in comparison withother boots they will not need repairs. f

I am aware that rivets placed in a continuous line have been used tojoin together the uppers of moccasns, and also that cement has been usedfor a like purpose, and therefore claim neither of these, broadly.

What I claim is as follows:

As an improved article of manufacture, a boot or shoe having the severalpieces forming the upper joined together by acontinuons line of rivetsand stitching, and having rubber cement placed between their meetingsurfaces, whereby I obtain not only water-proof seam s, but also apermanent union of parts, all

as herein set forth.
